[FAQ] Viewsonic G-Tablet ROMs Frequently Asked Questions (READ THIS FIRST)

Here are some frequently asked questions about the G-Tablet. Where there are specific answers based on ROM, the ROM is listed prior to the answer.
How do I install Clockworkmod?
See Step 1 of THIS POST
OR watch THIS VIDEO
How do I boot into Clockworkmod?
With the device completely off (and not asleep/suspended), press the + volume button and the power button until the device turns on. If it is successfully booting into Clockworkmod, you will see a message at the top left of the screen saying booting recovery image.
How do I perform a wipe data/factory reset?
With Clockworkmod, select the third option in the menu "wipe data/factory reset" and press the Home key (second button down on the right side of the gTablet in landscape view). Then, confirm wipe by selecting "Yes - wipe data/factory reset" and press the Home key again.
How do I clear the cache?
With Clockworkmod, select the fourth option in the menu "wipe cache partition" and press the Home key (second button down on the right side of the gTablet in landscape view). Then, confirm wipe by selecting "Yes - Wipe Cache" and press the Home key again.
How do I install VEGAn-TAB/TnT Lite/Cyanogenmod?
See the very first post of THIS THREAD
Where can I find the different ROMs for the G-Tablet?
1) Stock by Viewsonic
2) Stock + Performance Pack by rothnic
3) Tnt Lite 4.1 by Roebeet
4) VEGAn-TAB beta 5.1 by gojimi, Roebeet and Rothic
5) Zpad Clean 3.0 by rothnic
6) CyanogenMod 6.1 Beta4 by bekriebel
7) CyanogenMod 7.0 RC0 beta3 by bittrix
8) Tnt G-Harmony-Gingerbread Elements by tjohnsonjr
9) Plus the great kernel enhancement by clemsyn.
Keyboard and Mouse Support
VEGAn-TAB: Yes; supports an external keyboard and mouse, but it is picky. I have tested three keyboards; only one worked (MS Natural Keyboard). The MS Arc and an old Compaq keyboard did not. All mouses tested worked fine (both wireless and wired).
TnT-Lite: In testing; will update when testing complete.
Cyanogenmod 6.1b4: Yes; According to iammuze, keyboard and mouse both work.
Wallpaper blurry
Some have pointed to applications that can possibly fix this (Wallpaper Set & Save, MultiPicture Live Wallpaper) but I have had limited success with both of these. A bit of experimenting with different wallpapers will yield a satisfactory wallpaper image until this is cleared up at a later time.
Screen resolution in landscape (horizontal) mode
1024 x 600. Remember that if you're making wallpaper, when using the G-Tab in portrait mode (vertically) will make the wallpaper shrink and there will be black bars on top and below the image. Best image size: 1024 x 1024.
How do I get a fully working Marketplace?
See Step 3 of THIS POST
Is there a difference between the marketplace that comes with most G-Tablet ROM builds or the new "improved" market?
The only difference is the appearance. In functionality, it is the same. The market hack is still required for the new improved marketplace (and reports are that it often takes more tries to make work than the standard market).
Problems with acore FC's
The problem is a corrupt contacts sqlite database. As the referenced post says, you'll be able to tell if thats the problem when there is a .db-journal file in the folder. The folder is /data/data/com.android.providers.contacts/databases/ *Note* this is not the data folder in sdcard, but the data folder in root (/).
Just delete the databases folder in /data/data/com.android.providers.contacts and restart. The contacts database will be rebuilt and re-synced.
Also, see THIS THREAD/FAQ
Why do I keep seeing repartitioning as a solution to install problems?
Because Viewsonic didn't partition the G-Tablets in a way that Android likes to live on. By repartitioning, Android feels happier and many issues/problems are resolved.
What is the recommended repartition ratio?
2GB/0MB is STRONGLY recommended for TnT Lite 3.00+
2GB/256MB is considered the default setup
4GB/256MB is used by many people, but see the aforementioned caveat regarding TnT Lite.
Why won't one of the devs answer my question/post?
Because they:
1. Have day jobs.
2. Are busy coding and fixing the next release of VEGAn-TAB.
3. Have seen your question 23 times already in this thread: the search function is your friend.
4. Are not being paid to read forums and go through 100's of posts, many of which ask the same question (although they do this out of the kindness of their hearts thankfully!!!).
Who are the devs working on the G-Tablet
VEGAn-TAB: Gojimi, Rothnic, and Roebeet
TnT-Lite: Roebeet
Cyanogenmod 6.1b4: bekriebel
I can't get X to work on my G-Tab. Can you fix it? (where x = desired ROM)
Maybe. Maybe not. Currently, VEGAn-TAB is in Beta which means that it's still in testing. While it may be stable and usable for most people, it doesn't mean that it will be completely stable for you. If you have problems, post them and be happy knowing that you're helping the community at-large. Some problems may not be reproducible, however. In that case, it may be a matter of a corrupt install, conflict with previous install, cache or data issue, etc.
Do the dev's accept donations for their work?
Some do; others don't. If you see a donate button on their profile, feel free. If not, they don't accept them.
How to get the stock VEGAn-TAB wallpaper without the letters?
See attached image in 1024 x 1024.

More Advanced Questions.
Can the startup "Viewsonic Birds" or "gTablet" screens be changed?
Yes they can. Follow the instructions in THIS POST.

These were grabbed from over-the-air updates. They are full recovery images that wipes everything except the user data.
To use this with a vanilla recovery, you need to rename the file to update.zip, copy it to the root of /sdcard, and also create a recovery folder with a file called "command" (see the 1.00 release for that file). When you run recovery, the command file will direct recovery to run the update.zip to update the system.

1.0.0 homebrew link: http://forum.tegratab.com/viewtopic.php?f=6&t=16
This was developed by the user community to allow you to flash back to a vanilla setup, in case something goes wrong with a mod or if you want to return the item. This is the ORIGINAL firmware of the device, from early November.

Great FAQ!
"Why won't one of the devs answer my question/post?" is so true. I scan this forum daily, but there is no way to keep up with all the questions that pop up (especially once it's back more than 2 pages). If you really need me, PM me - at least I'll eventually see the question. But, keep in mind that I get more PM's than you might realize, so it could take me some time to respond.

@ehunyadi as Robeet said Great FAQ. This will definitely help alot of people.
Now I just need to find free time at home to test out the vegan ROM.
Maybe this should be a sticky?

Thanks, guys.
I tried to change the title of this thread to encompass all flavors of G-Tab ROMs but I think only a mod can do that.
I am going to start including info about all the different ROMs in here as well to help keep things simple in regards to finding the FAQ's in one place. This SHOULD help reduce the questions a bit. At least that's my hope.

Awesome job! Thank you so much for this! I posted your video of VEGAn-TAB on our new ROM homepage. Check it out @ HTTP://vegantab.gojimi.com.

Sure. I can put that in here. Give me some time; I'm having a busy day at work today.

ehunyadi,
I forgot about this thread, but you may want to see my thread up higher about a site I found which offers a .pdf of the Advent Vega manual and some software for those capable of working with it.
The manual explains operation of much of the ROM interface.

Oops, I had the link in memory and so I just pasted it in for you to look at.
Rev

I'd like to know/see in the faq what in the SDCARD folder is safe to delete
or how to do a complete wipe
and: Where do my installed applications go?

Thanks a lot for the FAQ Ehunyadi
You guys rock!!!

How do I install VEGAn-TAB?
See the very first post of THIS THREAD
Click to expand...

OK, I am a n00b to the Gtab scene. I do read the first post 99.9% of the time, but when the first post leads me to an incorrect first post about how to install, I must make mention of that fact. The first post mentioned does not have any instructions for installing. Is there a step by step tutorial for this to be found?
TIA ..... HTR

I see you added the link to the default wallpaper without the branding but what is the location of the default Vegan wallpaper or at least a link to it? I changed my wallpaper and now would like to revert but do not know the location. Thanks a lot.

Once you change it from the default, there's no known way to go back right now.
Edited to add: You can always use the image an image that is identical to what VEGAn-TAB comes with stock, but this has to be downloaded and selected from gallery/filesystem vs going back to the default wallpaper.

Good point; I'll fix that link.
As for a step-by-step, you can view THIS VIDEO that takes you through the steps of installing with Clockworkmod. Ignore the fact that it already has an OS on the G-Tab; you can do this with a fresh install as well.
Also, see THIS THREAD for step-by-step instructions. I'll fix the first post in the thread to reflect the change.

Here is the default Vegan wallpaper:

[ROM/WIP][ICS/US 9.2.1.11] 4.0.3 Minimal

This is my first attempt at a custom ROM for any Android device, so bear with me. I did not build this from AOSP source, or any other source code. It's entirely from ASUS. This ROM is intended for those who don't like the stock ASUS apps, similar to KRAKD/FROZN, except I've not optimised any of the APKs or anything else. Hopefully this can be a useful base ROM for another dev, taking the tedious part out of the equation. It's completely based on US, not WW or TW.
It's large(300Mbyte) because I used a binary blob. I'm working on shrinking it down with a proper update sript.
Apps I removed:
Amazon Kindle
MyCloud
ASUS File Manager
MyLibrary
MyNet
Netflix
News & Weather(and their widgets)
PolarisOffice
PressReader
MyZine
Tegra Game Zone
Web Storage
Zinio
PC Sync
ASUS Software keyboard(the touchscreen one, not the dock keyboard)
DMClient(related to ASUS updates, from what I understand)
ASUS software update(so no annoying OTA notifications that you can't use anyway)
SuperNote
-any others not included that I forgot to list
How to install:
1. A complete data wipe(at least dalvik & cache, data is optional) is strongly recommended if you're coming from Honeycomb.
2. Flash the zip from CWM.
3. Enjoy your new ICS.
You should be able to flash from any ROM if you clear at least dalvik and cache.
Features:
-Pre-rooted for your convenience, with busybox, su, and SuperUser.
-ALL bloatware removed, hopefully improving performance
-Closer to an AOSP experience due to all bloat being removed.
What this ROM does NOT have:
-Custom kernel
-Stock ICS buttons(it has the crummy ASUS back, home, recent app buttons)
-Zipaligned APKs
-Deodexed APKs
-A name, since it doesn't really need one right now.
How I created it(roughly, not a step by step):
1. I reverted from a custom ROM(krakd) to the latest US .21 HC release, with stock recovery
2. I Rooted with nachoroot and then used OTA keeper to unroot
3. I updated to US ICS via OTA.
4. I reapplied root with OTA keeper
5. I used ES file manager and terminal to remove the apps
6. I used ES file manager to add SuperUser to /system
7. Installed busybox at some point during these steps, I forget when.
8. Used dd to image the /system partition(mmcblkp0) to a file on my MicroSD
9. Replaced the LNX and APP blobs of a Honeycomb update(.21) with the ICS ones
10. Flashed it, and it worked.
So it's not a "proper" update, broken down into directories and such, but it does work.

Have you tested this at all?>

Yes, why? It worked fine on my TF101.

I think everyone is always a bit skeptical of a ROM that someone says openly is their first attempt and they have less than 10 posts on here..you are after all talking about potentially rendering a $500 device useless..people are usually right to exercise caution..when the developer cannot post in the dev section because his post count is too low!
But hey, that is how Paul Burton started here, though it was not his first ROM I am quite positive..

After flashing, not booting anymore, and as I I know what I am doing...unless my power cord just broke.

thanks I guess, but I can remove my own apps From a rom ......

Fair enough, I do admit I'm new to Android development, but I wouldn't release something without testing it on my own device first.

Did you do a full wipe? I installed it at least 5 times today during testing removing apps with no major issues..
BTW: Here is the MD5 for the zip: 0B9BC1C83C271DF26501CF533A046CB1
And the SHA1: B7BBC2C3AB33844E46CC8D8D2900E2AF1C68EFB5

Yes, although like I said. I know what I am doing. My power cord in fact, may have just broke. (Although I doubt it.)

IF YOU cant post links yet it's for a reason

cool, where did you get the source code from asus?

It sounds like he got the ROM and removed the third party apps, not that he got the source code to build it to AOSP.

its more a list of apps that are safe to remove with TB...... IMO anyway. Happy to wait and see if it leads to something a bit more though.

Lets make sure that no one will ever want to dev for us anymore by slapping the new guy around who took the time to try something himself. I recall Paul didnt have enough posts to start a thread in dev but he seems to know what hes doing. Why not just ban anyone whos new from ever posting any kind of dev work ever. Because what we need are more people making fun of and trashing someones work instead of people actually willing to take their time and try to make YOUR device nicer. Any wonder if this is why devs are leaving xda every day?
BTW..Just flashed this and it booted just fine. I did a system wipe first.
Maybe you should be the guy to add onskreen framework to a rom....hint

I didn't, sadly. I kludged it together somewhat by dding the fully updated ICS /system partition(adding busybox, su, Superuser beforehand) and making it into a blob that's flashable.

Correct.
Thanks for the feedback guys. If you want anything added, I'll try to accomodate with flashable zips since they're smaller to upload. My upload is horrible, so I can only upload a large ROM every once in a while(it takes over an hour!). I'm not discouraged, I know how it is to be the new guy. I know this rom's probably nothing special, but I just wanted to share what I'm enjoying with others.

Haha, it's not that custom, more of a repack with a bunch of removed apps, but I'll look into making it deodexed and stuff. I'm still learning how to do that.

Popping into a best buy and trying a different power cord when my friend gets here. Not trying to naysay. Just trying to troubleshoot.

Oh, I know. It's cool.
Hope you get it sorted out soon.

I'll try it out later (I got too many projects going on), but I appreciate your contribution.

As someone who has been around these forums and been messing around with ROMs for a while now (but has never posted before), I applaud the effort. THANKS.

[GUIDE][ROM FLASHING][WALK THRU][WIP] Easy to do!

This should help anyone who keeps having flashing issues.
THIS IS ONE QUICK/SIMPLE ERROR FREE ROM FLASHING PROCEDURE
Here is my quick rom flashing process I use ALWAYS (yes always)
THINGS YOU NEED ON SDCARD
1. Extra kernels (2 or 3 you know works for your device)
2. Optional: 2 recoveries that can be flashed (I use CWM & TWRP)
3. Optional: apps.zip (a zip created from Titantium BU, containing Root Explorer, TU Backup, Quickpic, ES File Explorer and Terminal Emulator)(OR WHATEVER YOU USE)
apps.zip not included. Create your own.
Flashing the rom:
1. Backup current rom (to the sdcard)
2. Complete wipe, (I do complete, some people do not) Complete = No Issues
[FACTORY RESET + CLEAR CACHE + CLEAR DALVIK CACHE + CLEAR SYSTEM]
3. Flash the rom
4. [TW roms this step is not needed] Flash gapps for aosp roms if applicable.
5. Boot the rom.
FINISHED!!!! SUCCESS!!!
Total time to flash a rom:
7-10min
Errors - NONE
TIPS:
I am in no way responsible for anything that may do damage to any device - Use these tips at your own risk - period!
If you found this useful in any way, please hit the THANKS button for my effort.

What's quick about this it's pretty much the same as any rom op

Not for the old timers, this is basically a quick ref for the newer peeps.
Most of us know these things, but there are others that don't.
Don't worry, the post will get buried sooner or later.
Thanks

thanks for writing this up.
maybe this would be a decent sticky for the QnA section?
maybe add a touchwiz section? an explanatinon of what aroma installer is? With a warning that some of the roms are close to 1gb in size? (at least when i tried some a while ago, not sure if they slimmed down.
adding that the OP is always a good source for info of any rom

just saying that the process is slightly different and the extra info would help
gapps not required mostly. buti t seems as if you added that, or i missed it earlier when i posted.

hehe I added it, by all means, if anyone wants to participate in adding anything to the guide, feel free to jump in with some advice, good things come from others.

[updated: 07-12-2013]

Recovery differences?
Does anyone have any opinion/knowledge on the differences between CWM and TWRP? I mean, I've used them both. I know the difference in appearance, and use. But is there any difference in reliability? Is one better for TW or AOSP? Is one more reliable? Better at different things? Some devs recommend one and some another. Opinions? Experiences?

[Q&A] [ROM][2.3.6] AEON v1.4SL STABILITY AT ITS FINEST

Q&A for [ROM][2.3.6] AEON v1.4SL STABILITY AT ITS FINEST
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer.
Before posting, please use the forum search and read through the discussion thread for [ROM][2.3.6] AEON v1.4SL STABILITY AT ITS FINEST. If you can't find an answer, post it here, being sure to give as much information as possible (firmware version, steps to reproduce, logcat if available) so that you can get help.
Thanks for understanding and for helping to keep XDA neat and tidy!

Where to go from here
Not sure what happened, hope this didn't get posted twice.
Hi,
I am still happily using the Samsung Infuse 4G, and was running the stock GB 2.3.6. No real issues, and although starting to get a sense of it being dated was having no issues and in no rush to go out and upgrade. However, we recently purchased a 2015 Subaru Legacy with their Starlink multimedia system. The Infuse, as it was with the stock GB had no problems connecting via BT for phone and audio functionality. But, the car system reports that the phone is not compatible for messaging. In my endeavors to understand why, I thought, maybe incorrectly, that GB does not support the MAP profile.
So, that led me to, is it possible to add that, and how do you do it, or is it time to upgrade? Flash a new ROM? I can't seem to find much on the specific issue I am trying to resolve and if a new ROM would fix it, but since the phone is way out of warranty I decided to try rooting and flashing a ROM. I am new to this so I went with the Aeon 1.4 ROM based on GB 2.3.6 (I think), hoping that it was a bit less risky. Everything went well and seems to be working fine. But, it did not fix the messaging issue with the car. I assume because it is really still GB.
Am I going about this wrong? Would a flash up to ICS or beyond possibly do it? I am not totally against a new phone, but till now I wasn't even thinking about a new phone. Suggestions? Which ICS, or other ROM would you recommend? Thanks all.

I think your car requires the newest bluetooth protocol (4.0), something that is primarily hardware based.
I could be (and hopefully am) wrong here, but the only way to find out is to do a ROM walkabout.
ICS is out right off the bat, as bluetooth was borked in that version (IIRC). You'll need to upgrade to that in the process anyway, as CWM for this device doesn't like drastic changes.
I am biased, but I would try CarbonROM 4.4.4 (the latest, unofficial build) or at the very least CM 10.1. The former would have the best chance of support (being latest firmware available), but it may be overkill for your situation (newer versions = harder on battery life).
So I would try CM 10.1 after stepping up to ICS (having done a full nandroid before all this), and if the car still refuses to connect, try Carbon. Then you may be able to prove me wrong.
Hope this helps.

Thanks very much for your reply.
Being a hardware issue is something I have considered, but not knowing enough to understand why it might work virtually flawlessly for phone and audio streaming in the car, I was hopeful the hardware would support additional Bluetooth profiles, that are added with a new ROM. But then again, I would not be surprised to do the walkabout and end up at the store for a new phone in the end anyway.
I will be looking for an ICS ROM, but it sounds like it doesn't matter which one I use because I won't be staying there?
I have done, and will do again, backups, but I am little unclear on a few things. CWM is on the phone, but I actually used ROM Manager for the flashing I've done. Are they the same thing? It uses CWM. Also, I've seen various references to making sure the phones identity (not sure that's the right term) is saved, and I take that to mean that after flashing the phone may no longer be able to access phone carrier service. Is that a real possibility? And, is it necessary to remove the SD card? Thanks again.

I would recommend Entropy's ICS build, which I have a mirror of, accessed from my signature link.
ROM manager loads CWM (same author, ROM manager is IIRC just the Play Store delivery mechanism for CWM), so once you have CWM, you are good to go for your walkabout.
Yes, you want to make sure to back up your IMEI information first, because that stuff can get lost, which if lost, will deny you access to your carrier. There is a way to retrieve it if lost on this device, but an ounce of prevention is worth a pound of cure. Check the CM10.x thread on instructions how to flash (with links to the IMEI backup).
No need to remove the SD card, but if you don't need it for a flash, I would remove it anyway (or back up it's contents to your PC first - in case in the unlikely event - I'm paranoid about those things - CWM goes a little liberal with the factory reset).
Hope this helps.

Thanks Joel. I have now installed Entropy. Don't know whether everything else is working, but I do know that I can not connect to my wifi. Keep getting "authentication problem." I see that it is a known problem, but I'm not finding a solution. Not quite ready to go the next step (time constraint), so I'm hoping there is a fix, or at least a workaround. Kind of a bummer not having access to wifi. Any suggestions?

I wouldn't worry about it. Entropy is just a step-through (because BlueTooth is broken as well) and there are other ways to get the other ROMs onto the device (if they are not there already) such as adb push or MicroSD + Built-in Filemanager App. Higher versions will have that fixed anyway.

Downloadable CM 10.1

I don't have a lot on my data plan, so I rely on wifi quite a bit. But for now, not a big deal and will try to upgrade asap. No issues with getting the file to the phone, but I am having some difficulty finding a downloadable CM 10.1 (actually it is 10.2), and a gapps file for it. The XDA forum I went to doesn't work and if I go to the mirror site it tells me the file is too big or something and I'm not able to download. Haven't scoured the internet looking for it, thought I might save some time if you know where I can get it. If not, I'm thinking just try the Carbon ROM, assuming I can find it. I know you recommend CM first. George

Hi George,
My signature link contains the CM10.1 ROM (and Gapps) as well. I had problems with CM10.2 back in the day (wouldn't install), so I would recommend 10.1 over 10.2.
My Dropbox may be exhausted for the day (sometimes it gets like that) but I may have a copy on well, Copy, that I could send if necessary. Just let me know if you have problems downloading from my mirror first.

Joel,
Maybe I'm just missing something. Not having a problem downloading, I'm having a problem finding the files to download.
The only link I find (it's the link that says something about development files?) takes me to the XDA CM 10.2 forum where I wasn't able to get it. Maybe I'm just missing it in your signature links. I see references to Carbon and other stuff. George

Hi Joel,
Got it upgraded to CM 10.1. All seems well. Unfortunately, it did not fix the compatibility problem with messaging and our car, as you correctly suggested might happen. Is there anything about Carbon that gives you reason to think it might work? As I said in the original post, I made some assumptions about the problem (Bluetooth MAP profile based on some reading), and that might be a software fix. But, of course, I may be completely wrong about it. Thanks. George

Hello again George,
Nothing about Carbon in general, but KitKat, yes...
Android 4.4 support for two new Bluetooth profiles to let apps support a broader range of low-power and media interactions. Bluetooth HID over GATT (HOGP) gives apps a low-latency link with low-power peripheral devices such as mice, joysticks, and keyboards. Bluetooth MAP lets your apps exchange messages with a nearby device, for example an automotive terminal for handsfree use or another mobile device. As an extension to Bluetooth AVRCP 1.3, users can now set absolute volume on the system from their Bluetooth devices.

I guess it couldn't stay easy. My attempt to install CARBON (two different download versions) failed, I am getting an error I don't understand.
First, when I go to wipe dalvik I get E: unknown volume for .... (/sd-ext) I can not read it very well because of the background image. Where I put the ... it looks like path.
Then
This ROM uses an imcompatible partition layout
Your /data will be wiped upon installation
Run this update.zip again to confirm install
Then
assert failed: run_program("/tmp/updater.sh") == 0
E:Error in /sdcard/CARBON-KK-NIGHTLY-20141102-0915-infuse4g.zip
(Status 7)
Installation aborted.
Any ideas what this means? I can reload CM 10.1, so I am not bricked or anything. I appreciate your help.
I did try to get some help from the IRC forum at CARBON, but haven't gotten any replies.

There's this tutorial (section 27), but what may be happening is a drastic change in ROM's for CWM (which falls under what status 7 error scope - along with corrupted IMEI, etc).
My upgrade path long ago (coincidentally) was Stock -> CM9 -> CM10.1 -> Beanstalk 4.4.2 -> CarbonROM 4.4.4.
You can, however cheat, by disabling voodoo lagfix in CWM settings. Otherwise, you may need to find the oldest CarbonROM Kitkat you can grab (4.4.2), to make that last (small) jump to 4.4.4.
If still doesn't work, roll back to CM10.1, make sure everything is order (including calling), and try again.

I may have to bag this whole project. Must be a little late doing this. Too much time and trouble searching for files that can't be downloaded. I could not find an early CarbonROM KitKat to download. I could not find a BeanStalk to download. I find links that point to a defunct website. I did finally find a CM11 which I did download, but I did not see a gapps file to go with it, unless I can use any 4.4 gapps. Also, when I run CWM there is no reference to lagfix. I appreciate all the help, but I don't want to take any more of your time. George

Hi George,
Any 4.4.2 Gapps will work. I am uploading one right now (along with older Beanstalk and CM11)...
https://www.dropbox.com/sh/smohomrdx0oqn76/AACfrsgXTEHhDmVtwEWj6EA5a?dl=0
...it may take an hour for files to appear, so keep posted, if still interested.
Also, another way to disable voodoo lagfix (if not found in CWM) is to create a folder on internal storage called Voodoo, and then a folder inside that called disable-lagfix.
Hope this helps.

Hi Joel,
Unfortunately, none of these 4.4.x versions will install, same error. And placing Voodoo/lagfix/ folder doesn't seem to work either, same error. If the problem is the jump to the next version is too great, maybe an earlier version of something, 4.2 or earlier? George

OC-K1 Nougat

3.0
given up using peoples dirty code, so downloaded nvidias dirty code instead lol
cleaned the code up best i could, things ive noticed while playing games on the tablet is -
when i play "nitro nation" the first race no longer stutters
when popups appear they dont take a while to appear..
when i play "word mind" it doesnt take ages to load with crackling sound
when using "kernel auditor" if you set the GPU max and min values high (i only did this trying to keep the values standard), when the GPU gets hot, it cant scale down the GPU frequency so it starts trying to kill tasks.
i dont think you need to download/flash blobs as they are for flashing binary stuff, but i cant find a need for it, think its more of a precaution to ensure the kernel boots.. but dont think i have flashed them
-----------------------------------------------------------------------------------------
3.1 : FINAL,
dunno what changes i made but ive recently upgraded my tablet so figured id upload my latest and last
obveously i have had to start again running 3.10.96 but done alot of work to make it as fast as i can so far, but i deleted all references to my old code and cant find them anymore,
GPU is now at 914 MAX as ive found its the GPU that generates a lot of heat, which causes it to throttle, and found values higher than this just degraded performance.
ive known for a long time that "DT2W" works great while connected to USB, due to the custom USB wakelock, i know the app "wakelock revamp - power manager" would resolve it. but ive found tapping where "notifications" would be wakes the screen (ive found bottom right where the camera would be is a good spot) im trying to figure out how to apply the wake lock better.
scores on PCMARK are above the scale on most values
scores on 3DMARK are around 3250 ~ 3320
=========================================
if you want to create your own, i created a guide, also the website i used to help me understand
https://************/how-to-build-android-kernel-on-windows-10/ appuals . com
-----------------------------------------------------------------
Thanks to :
-----------------------------------------------------------------
"hazel nut" for his support, as if he never said "cant wait for it to come out" i dont think it would of pushed me so much
----------------------------------------------------------------
"BitOBSessiOn" for his source code
https://github.com/BitOBsessiOn/android_kernel_nvidia_shieldtablet
-----------------------------------------------------------------
"laufersteppenwolf" for his source code and commits to overclocking and DT2W/STW
https://github.com/laufersteppenwolf/android_kernel_nvidia_shieldtablet
-----------------------------------------------------------------
"Christopher83" for his cross compiler
https://github.com/Christopher83/arm-cortex_a15-linux-gnueabihf-linaro_4.9
-----------------------------------------------------------------
Microsoft, if i didnt hate windows 10 so much, and didnt get a message regarding dropping support for windows 7,
i would still be using a virtual machine which due to it being so slow, i would of probably given up a long time ago
----------------------------------------------------------------
thanks to everyone that has said thank you

Nice to see that you open a thread.
Appreciate a bit companionship here.
In your guide didn't you specify how you create thr zip file.
I used the nethunter installer, which is based on lazy flashed in regard of the external modules, this come in handy, but I found relatively little among the Shield kernel support.
I noticed that you set the make command with the addition of the specifications of the number of CPUs, which are to be used, before every command.
Is this a typo, or is this the correct procedure when you compile with Windows?
Did you mean with
"bin-bash-command"

That's just how I make the command, as if you tap the up key, you can scroll through previous inputs, if it makes it faster- that's a bonus.. but you're right about being very little support.
With regards to the zip file - you could use mine or any other zip that is a kernel flash - as long as you drop it into the kernel folder.. I believe there is an "anykernel.zip" somewhere if you prefer to use that.. also if you wish to add your own personal touch, you can modify the script file in the metadata folder

Response
I also chose different colours in the guide and placed it in a separate line so people could understand the exact typing.. or they could copy and paste..
But with regards to support it is one of the reasons I made the guide, in hopes the Nvidia community could follow it, understand how to achieve their own kernel, and improve the tablet. As there seems to be a serious lack of support..
I had to learn on my own, through Google and YouTube, but hopefully this will speed up what took me a month of trial and error..

Is it compatible with stock based fw (5.4)? Just need to flash blobs, then kernel and reboot?

Respond
Yeah, extract the blobs before flashing.. only available for stock/stock+ rom

Oh, by the way, you can’t compile with windows unless you’re using a virtual machine.. has to be Linux/terminal

Thank you, I will try out as soon as I can get to my computer. I have downloaded the wakelock v3 app and kernel adiutor an I can't enable wakelock in kernel adiutor (I can't see any option for it). Only this new kernel will support this option, am I right?

You must of done something wrong as “wake” is below “gpu”
You extract> then flash the blob at the fastboot menu via typing - fastboot flash staging <blobfilename>
Then via TWRP recovery you install the “OC K1” kernel without extracting.. I have 3 tablets and it’s worked on them all.. hope this helps,

Thanks for letting me know, originally you wouldn’t of needed the “wake v3” app, but I started fresh, which gained performance, and I decided to look for an easier way to stop the tablet “deep sleeping” on me.. less of a headache this way :laugh:
